"Specification of llmtt'ers latent. Pajtente'fl Nov, 29 1910,Application filed December 3, 1909. Serial No. 531,270. I

To all whom it may concern:

Be it known that I, GO'I'IFRIED MEYER, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented a new and useful Process of ManufacturingFlexible Tubes for Fountai' Paint-Brushes and the Hike, of which thefollowing is a specification.

This-invention relates to a new and improved process ofpreparingflexible tubes of that type used in connection with fountain paintbrushes and the ike. Tubes of this character have heretofore beenaffected to such an extent by the paints directed through them, as torot or'become eaten and thus rendered useless.

The object of the present invention is to produce a tube which willwithstand the action of the paints-and will remain flexible as long asused.

The invention consists in treating the intestines of goats, sheep,swine, etc, by cleaning them and then impregnating them with a suitablepreservative whereby a soft flexible tube is obtained which may beutilized in connection with tubes of other material for the purpose ofobtaining a complete hose for the purpose stated.)

The invention also consists of certain,

novel features hereinafter more fully described and pointed out in theclaims.

In carrying out the invention, the intestines, after being removed fromthe animal,

are turned inside out and, after being thoroughly cleaned, are placed ina mixture of hours so as to become thoroughly saturated.

water and sodium sulfid, there being preferably about one per cent. ofthe sodium sulfid in the mixture, although a stronger mixture willproduce quicker and equal results. This mixture combines with thosesubstances contained within the intestines and which tend to render themhard and brittle unless removed. As a result of utilizing this mixture,the intestines are rendered soft and flexible. The intestines aresubjected to this treatment for from two to three days, according totheir toughness. They are thenthoroughly washed to remove thecomposition and are subsequently drawn over a coiled wire or the likewhich keeps them stretched 0 en. While on this coiled wire, they are paced within cold glycerin and retained therein for from three to sixThis completes the preparation of the intestines and after they havebeen wiped dry subseguent to the glycerin treatment referre to, they maybe placed within atube of fabric, rubber or any other material and thecoil then removed.

In order that the sections of intestines may be connected to form a tubeof desired length, it is necessary to insert one edge of each sectioninto an end of the adjacent section and to cement the sections together.For this purpose a special form of cement may be employed, this beingmade up according to the following formula:

White wine vinegar 1/100 part.

This cement is prepared by soaking the glue and gelatin in water and byadding the vinegar, after which the mixture is boiled. The glycerin isadded while the mixture is boiling, it being necessary to keep themixture stirring constantly. Acetate of alumina may be added to themixture after it has been removed from the fire, in order to, keep it ina flexible condition.

It has been found that a hose made of a tube lined with intestinestreated in the manner herein-described, is capable of resisting to theutmost the corroding action of paints and the like, and the principalobjection to the use of tubing in fountain paint brushes is" thuseliminated.

What is claimed is 1. The herein described method of producing' tpbesfor use in connection with fountain paint brushes and the likeconsisting in subjecting the intestines .of an animal to the action of amixture of sodium sulfid and water and then treating the intestineswith, glycerin.

2. The herein described method of producing tubes for use in connectionwith 100 stretching the same upon an expanding coil, 05

and then treating the intestines with glycerm.

3. The herein described method of producing soft flexible tubingconsisting in sub jectingthe intestines of an animal to the cc 0 tion ofa mixture of sodium sulfid and water, as my own, I have hereto aflixedmy signatgen greeting Ithe ingestines dwithb glyceriii, ture in thepresence of two witnesses. t en r in t e pro not an su sequenty vuniting {he intestines with a cement consist- GOTTFAIED MEYER 5 ing Ofglue, gelatin, glycerin, white vinegar Witnesses:
